Sand Hills Judkins Unit #11 (API 42-103-32532) is a well in Crane County operated by Vanguard Operating LLC, completed September 1, 1981.

The RRC has issued 2 drilling permits between 1981 and 2005, permitted to 3,300 ft.

It was permitted by Encore Operating, L.P. and has since transferred to Vanguard Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including San Andres, Judkin.

Its 2 leases have reported 22.8K barrels of oil and 556K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
